Initial Project Setup

Configuration tasks that must be set up prior to the following workflow sequence are carried out on the AVEVA Clash Manager Configuration window - Project tab, refer to Clash Manager Configuration for further information.

Check for Clashes and Resolve Them

The initial situation is that there are sufficient items built in the 3D Model to necessitate checking whether or not any of them clash and, if so, nominating who is the discipline designer responsible for resolving the clash(es).

The general principle of assigning the responsibility for the resolution of a clash is that it should rest with the discipline associated with one or other of the clashing elements. Another discipline can be assigned, where appropriate.

A special Clash Set, named 'Default' may be created, which will be used as a template for all personal clash sets that are employed when the Clash Check CE option is selected. Refer to Clash Management Options for further information.

Before a clash check can be run the items to be included have to be specified which means a clash set must be created and essentially contains two lists of items.

The first list consists of items that are considered to be obstructions (usually steelwork or structure items). The second consists of items that might possibly clash with the obstructions.

Select the contents of the lists in the clash set to be run, together with other details such as the co-ordinates of the space occupied by the clash set, on the AVEVA Clash Manager - Clash Sets window. Refer to Prepare Clash Run for further information.

There may be several clashes in close proximity to each other between an item and an obstruction. For example, a pipe running approximately parallel with a steelwork item may hit it several times. It should be considered how to handle this type of event, because to report every clash may provide more detail than is desirable. For example, an engineer may consider these multiple clashes as one big clash and resolve it accordingly.

AVEVA Clash Manager provides a method of combining such clashes into Clash Groups, and reporting on these, as well as on the individual clashes. The configuration task for specifying how the Clash Groups are to be organised is carried out on the AVEVA Clash Manager Configuration window - Group tab. Refer to Clash Management Options for further information.

Auto-assign Discipline

When both elements of a clash belong to the same discipline, members of that discipline are probably responsible for resolving the problem. However, when two disciplines are involved, it is not obvious which one is responsible (that is, which one is the owner discipline).

To avoid unnecessary manual action, AVEVA Clash Manager provides a method of automatically assigning the owner discipline to a clash. For the Clash Group, the owner discipline can be set to that of the ‘Worst Case’ clash in the group.

Setting up the Auto-assignment process and its associated Class, Level/Type and Priority considerations is configuration task performed on the AVEVA Clash Manager Configuration window - Assign, Discipline, Class, Level/Type, and Priority tabs.

Auto-accept Clash

Certain items may clash by design, for example, cables entering a junction box. AVEVA Clash Manager sees these as clashes, but the design engineers would not wish to take action and, in other words, would Approve the clashes.

For clashes of this kind, AVEVA Clash Manager provides a method of automatically approving them. The process is based on rules that, if satisfied, result in the clash being automatically allocated a status, such as Approved. The rules also enable specific comments to be attached to the record of the clash to indicate why it was automatically accepted.

The Auto-Acceptance rules and comments are set up as a configuration task on the AVEVA Clash Manager Configuration window - Accept, Status and Comments tabs.

Before running the clash check, specify a number of features that determine how the clash check operates. Also, specify the colour-coding of clashing elements in the Clash Reports and in the corresponding display. These actions are carried using the AVEVA Clash Manager - Customise window, refer to Customise window for further information.
